【Example】

 FIG. 1 is a block diagram showing an electrical configuration of a lighting control device according to an embodiment of the present invention. The AC power supply 1 energizes a plurality of lighting load circuits including lighting loads 2 and 3 such as lighting lamps. One end of each of the lighting loads 2 and 3 is connected to one end of the AC power supply 1. The other ends of the lighting loads 2 and 3 are connected to the other end of the AC power supply 1 via the main controller 4. The main control unit 4 energizes the respective lighting loads 2 and 3 at a dimming level that is combined in correspondence with the lighting pattern set in advance for each scene. Each lighting load 2, 3 is controlled by a switching element 5, 6 such as a bidirectional three-terminal thyristor connected so as to form a closed loop with the AC power supply 1. When the illumination loads 2 and 3 are incandescent lamps, the phase is controlled within the range of the dimming level of 0 to 100%. When the lighting loads 2 and 3 are fluorescent lights, etc., they are controlled to blink so as to be turned on or off.

The main controller 4 is provided with control means 7 for controlling the phase of the switching elements 5 and 6. The control means 7 is composed of a microcomputer including a central processing circuit (abbreviated as “CPU”) and a memory. The control means 7 is provided with a dimming switch 8 for setting a dimming level for activating each dimming load circuit for each scene, and a blinking state of the lighting loads 2 and 3 to be controlled depending on the blinking state. Input means 12 is connected, which comprises a blinking switch 9 for setting and scene switches 10 and 11 for selecting a set scene. The dimming switch 8 and the flashing switch 9 are provided for each of the lighting load circuits including the lighting loads 2 and 3 by the number of lighting load circuits. The scene selected by the scene switches 10 and 11 is displayed by a light emitting diode (hereinafter abbreviated as "LED"). The display means 15 including the scene selection display LEDs 13 and 14 is provided adjacent to the input means 12 on the operation panel surface of the main controller 4, and particularly, the scene switches 10 and 11 and the scene selection display LEDs 13 and 14 are provided. It is attached at a position corresponding to each scene.

The dimming control state of the lighting loads 2 and 3 input by the input means 12 is installed by the main control unit 4 via an interface circuit (hereinafter abbreviated as “I / F”) 16. It is transmitted via a signal line 18 to a remote control operation device 17 which is a remote control device installed in a room different from the room.

In the remote control operating device 17, the signal transmitted from the main control device 4 via the signal line 18 is received by the I / F 19, and the control means 20 determines the content of the signal. The control means 20 is composed of a microcomputer including a CPU and a memory. The control means 20 is connected to an all-off switch 21, an input means 24 including scene switches 22 and 23, and a display means 27 including scene display LEDs 25 and 26. On the operation panel of the remote control operating device 17, input means 24 and display means 27, scene switches 22, 23 and scene display LEDs 25, 26 are provided at positions corresponding to each scene.

The scene selected by operating the scene switches 10 and 11 of the main control device is transmitted to the control means 20 of the remote control operating device 17 by a signal via the signal line 18, and is used for scene selection display. It is displayed by the LEDs 25 and 26. When the scene switch 22 or 23 corresponding to the LED 25 or 26 indicating that a scene is selected is operated, the selected scene is switched off from the control means 20 via the I / F 19 to the signal line 18. A signal is derived that represents the fact that it has been manipulated. The control means 7 of the main control device 4 receives the signal via the I / F 16, turns off the lighting load circuit energized in the selected scene, and lights the scene selection display LED 13, 14 is also turned off. When any one of the scene switches 22 and 23 of the remote control operating device 17 is operated in such an all-off state, a signal is given from the remote control operating device 17 to the main control device 4 via the signal line 18. The control means 7 reproduces the corresponding scene, and the display means 15 displays the selected state. In this way, either one of the main control device 4 and the remote control operating device 17 can select each scene and make a transition to the all-off state.

The main controller 4 sets the dimming level or blinking state of each lighting load circuit when one of the scene switches 10 and 11 is operated to select a scene. It has a dimming switch 8 and a blinking switch 9. The set operation states of the dimming switch 8 and the blinking switch 9 are stored in the memory included in the control means 7 for each scene, and each time the scene is selected, each lighting load circuit is attached according to the stored contents. Energized. When none of the scenes is selected, the lighting loads 2 and 3 are not energized, and the lighting load circuit is turned off. When the dimming switch 8 or the flashing switch 9 is operated in the all-off state, the lighting loads 2 and 3 of the corresponding lighting load circuit are controlled to be turned on. The main control device 4 is installed in a room where the lighting loads 2 and 3 are installed, and the desired lighting loads 2 and 3 can be turned on by operating the dimming switch 8 or the lighting switch 9 with all lights off. . In the room where the lighting loads 2 and 3 are installed, it is possible to directly check the lighting state, and by turning the dimming switch 8 or the blinking switch 9 back on, the lighting state of the lighting loads 2 and 3 is turned off. Can be returned to. That is, in the all-off state, the dimming switch 8 or the blinking switch 9 operates as a lighting means for temporarily lighting the lighting loads 2 and 3.

In the room where the remote control operating device 17 is provided, such a temporary lighting state of the lighting loads 2 and 3 cannot be directly confirmed. Therefore, the control means 7 of the main control device 4 sends a signal indicating a temporary lighting state to the control means 20 of the remote control operating device 17 via the signal line 18. The control means 20 blinks the scene selection display LEDs 25 and 26 included in the display means 27 to indicate that they are in a temporarily lit state. As a result, it is possible to know that the lighting load is temporarily turned on without directly checking the lighting loads 2 and 3. When the all-off switch 21, which is all-off means, is operated in this state, a signal is given from the control means 20 to the control means 7 via the signal line 18, and the lighting loads 2 and 3 that have been temporarily turned on are turned off. It is controlled so that it goes off. At the same time as deriving such a signal, the control means 20 stops the display of the temporarily lit state on the display means 27 and makes the display of the all extinguished state. In this way, the remote control operating device 17 can also display the temporarily lit state and transition to the all-off state.

FIG. 2 is a flow chart for explaining the operation of main controller 4 in the embodiment shown in FIG. In step a1, control is started. In step a2, it is determined whether or not all lights are off. If all lights are off, go to step a3. In step a3, it is determined whether or not any one of the individual lighting load circuits is turned on. When any one of the lighting load circuits is in the lighting state, a signal indicating the temporary lighting state is transmitted to the remote control operating device 17 through the signal line 18 in step a4. When step a4 is completed, when it is determined in step a3 that all of the individual lighting load circuits are off, or when it is determined in step a2 that they are not all off, the process proceeds to step a5.

At step a5, the process waits until an input for selecting a state for dimming control is made by the scene switch. When the scene switch is operated, it is determined in step a6 whether or not a signal for turning off the selected scene is received from the remote control operating device 17. When the all-off state is received, the process moves to step a7, and the lighting load circuit is turned off. In step a6, when the all-off state is not received, the selected corresponding scene is output in step a8, and the lighting is adjusted so that the dimming level or the blinking state set for each lighting load 2 or 3 is achieved. The pattern is reproduced. After the end of step a7 or step a8, the control returns from step a9 to step a1 again, and the control is circulated thereafter.

FIG. 3 is a flow chart for explaining the operation for the control means 20 of the remote control operating device 17 in the embodiment shown in FIG. 1 to display the temporarily lit state and control the all-off state. In step b1, the signal representing the temporary lighting state generated in step a4 of the flowchart shown in FIG. 2 is received. Next, in step b2, the scene display by the scene selection display LEDs 25 and 26 of the display means 27 is blinked to indicate that the scene is temporarily turned on. Next, in step b3, it is judged whether or not there is an input from each of the switches 21, 22, 23 of the input means 24. When there is no input, the process returns to step b2 again. Next, in step b4, it is determined whether or not all the extinguishing switches 21 have been operated. When the all-off switch 21 is operated, a signal indicating the all-off state is derived to the main control unit 4 in step b5, and the scene display blinking is stopped. If it is determined in step b4 that the all-off switch 21 has not been operated and one of the scene switches 22 and 23 has been operated, the process proceeds to step b6 and a signal representing the state of the selected scene is transmitted. The display on the display means 27 is the display of the selected state of the scene. When step b5 or step b6 ends, the process in the remote controller operating device 17 ends in step b7.

FIG. 4 is a state transition diagram for explaining transition of operation states in the embodiment shown in FIG. When no scene is selected, it is in the all-off state or the temporary lighting state. When all lights are off, all lights are displayed. When all lights are on, temporary lights are displayed. From the all-off state, the flashing switch or dimming switch for each lighting load circuit is operated to shift to the temporary lighting state. From the one-time light state, the scene switch corresponding to the blinking scene selection display LED is operated to shift to the all-off state. By operating any one scene switch from either the all-off state or the temporary-on state, the scene turns on. At this time, the scene selection LED is turned on to indicate that the scene is selected. When the flashing switch or dimming switch for each lighting load circuit is operated while the scene is on, the scene correction state is entered to correct the lighting pattern for each scene. When the scene switch whose corresponding scene selection display LED is lit is operated in the scene correction state, it goes to the all-off state. When the scene switch for which the scene selection display LED is not lit is operated, the scene selection display LED corresponding to the operated scene is switched to the scene lighting state corresponding to the operated scene. When the scene switch corresponding to the illuminated scene selection display LED is operated in the scene lighting state, the scene selection display LED is turned off and the illuminated scene selection display LED is turned off.

As described above, when the scene selection display is displayed, it is possible to turn off all lights by operating the scene switch corresponding to the illuminated scene selection display LED. The scene lighting state can be selected from the temporary lighting state by operating the scene switch.

In the embodiment described above, the remote control operating device 17 is provided with the all-off switch 21, but any one of the scene switches 22 and 23 is controlled from the temporarily lit state to the all-off state. It can also be preset as a switch for doing so. If the blinking display of the scene selection display LEDs 25 and 26 is performed corresponding to the predetermined scene switches 22 and 23, the operation for completely extinguishing the lights can be correctly performed.

The display of the selected scene is performed by turning on the scene selection display LEDs 13, 14; 25, 26 provided corresponding to the scene switches 10, 11; 22, 23. Each scene is composed of two sets of display LEDs, etc. that have ON and OFF display elements. When all lights are off, the OFF display LEDs corresponding to all scene switches are turned on, and when all lights are on, all lights are turned on. Of course, the OFF display LED and the ON display LED corresponding to the scene switch may be alternately blinked.

Although the dimming level or blinking state for each scene is set by the dimming switch 8 or the blinking switch 9, it may be set by means such as a variable resistor. Of course. The switching elements 5 and 6 may be other semiconductor switching elements such as transistors or relays.
